Switching On and Off
To switch on the measuring tool, briefly press the On/Off button 7 or measuring
button 12. When switching on the measuring tool, the laser beam is not switched
on yet.
To switch off the measuring tool, press the On/Off button 7 for a few seconds.
If none of the measuring tool buttons are pressed for approx. 5 minutes, the
measuring tool switches off automatically in order to extend the service life of
the battery.
When a measured value has been stored, it is retained in automatic switch-off
mode. When switching on the measuring tool again, "M" is indicated in the dis-
play.
Measuring Procedure
After switching on, the measuring tool is in the length measurement mode. Other
measuring modes can be switched to by pressing the respective function/mode
button (see "Measuring Functions", page 20).
After switching on, the rear edge of the measuring tool is preset as the reference
level for the measurement. To change the reference level, see "Selecting the Ref-
erence Level", page 20.
Upon selection of the measuring function and the reference level, all further
steps are carried out by pushing the measuring button 12.
With the reference level selected, place the measuring tool against the desired
measuring line (e.g. a wall).
Push the measuring button 12 to switch on the laser beam.
Do not point the laser beam at persons or animals and do not look into the
laser beam yourself, not even from a large distance.
Aim the laser beam at the target surface. Push the measuring button 12 again to
initiate the measurement.
In the tracking function, the measurement already starts upon first actuation of
the measuring button 12.
Typically, the measured value appears after 0.5 and latest after 4 seconds. The
duration of the measurement depends on the distance, the light conditions and
the reflection properties of the target surface. The end of the measurement is in-
dicated by a signal tone. The laser beam is switched off automatically upon com-
pletion of the measurement.
When no measurement has taken place approx. 20 seconds after sighting, the
laser beam is switched off automatically to save the batteries.
Selecting the Reference Level (see figures A–C)
For measuring, you can select between three different reference levels:
– The rear measuring-tool edge (e.g. when measuring onward from a wall),
– The rear positioning-pin edge 14 (e.g. when measuring from a corner),
– The front measuring-tool edge (e.g. when measuring onward from a table
edge).
To change the reference level, press button 9 until the requested reference level
is indicated on the display. Each time after switching on the measuring tool, the
rear end of the measuring tool is preset as the reference level.
